Obstacles, rationally designed combinations of drugs targeting Immunosuppressive cells, modulation of immune checkpoints,Īnd impaired IFNγ signaling, among others3. Including increased expression of metabolic mediators, impairedĪntigen presentation and T cell activation, recruitment of Proposed tumor-intrinsic and extrinsic mechanisms implicated, Immunotherapy is the subject of intensive research, with several Observed response lacks durability due to the development ofĪcquired resistance2. Some cancers, many patients fail to respond to CPI entirely, or the Despite the impressive clinical outcomes achieved for Monotherapy or in combination with current standard of care Significant clinical activity in many cancers, either as Mmune checkpoint inhibitors (CPI) targeting the CTLA-4.

The engineered CD80 variant fusion therapeutic davoceticept combines checkpoint antagonism with conditional CD28 costimulation for anti-tumor immunityĠ Alpine Immune Sciences, Inc. We demonstrate that by combining CD28 costimulation and dual checkpoint inhibition, ALPN-202 enhances T cell activation and anti-tumor efficacy in cell-based assays and mouse tumor models more potently than checkpoint blockade alone and thus has the potential to generate potent, clinically meaningful anti-tumor immunity in humans. To address this, here we utilize directed evolution to engineer a CD80 IgV domain with increased PD-L1 affinity and fuse this to an immunoglobulin Fc domain, creating a therapeutic (ALPN-202, davoceticept) capable of providing CD28 costimulation in a PD-L1-dependent fashion while also antagonizing PD-1 - PD-L1 and CTLA-4–CD80/CD86 interactions. In some cases, poor responses to checkpoint blockade have been linked to suboptimal CD28 costimulation and the inability to generate and maintain a productive adaptive anti-tumor immune response.
